MANIFOLD-HEATER Fon. INTERNAL-COMBUSTION ENGINES.

To all whomfma concern: Y

Be it known t at We, JAMES F. PIER-GE and HAYNER VH. Groenen, citizens ofthe United States, and residents of Washington, District of Columbia., have invented certain new and useful Improvements in Manifold-Heaters for Internal-Combustion Engines, of Vwhich the follovving'is a specification, reference being had therein to the accompanying drawing.

The present invention relates to a device, the function of which is to facilitate the easy starting of internal combustion engines during cold Weather, the same being adapted to supply heat to the intake inanifold'of the engine so as to cause vaporization of the fuel mixture contained therein.

In devices of this nature heretofore used, it has usually been necessary to either use a manifold of special construction, or else to remove the manifold from the motor in order to do suitable machine Work upon the same to provide the necessary means for heating the mixture.

It is the general obj ect of this invention to provide a simple heating device, comprising a structure Yadapted to be clamped against the exterior of the manifold by a simple clamping means for the purpose'of supplying heat to the mixture contained therein.

l Other objects of the invention will appear as the construetionfis kInorezfully disclosed.

For the purpose of rendering the invention more clear, reference is had to the accompanying drawings in which Figure 1 shows a form of the invention as adapted for use in connection with the manifold of a Ford engine. F ig. 2 shows the bottom or under surface of the structure shown in Fig. l, Fig. 3 shows a side elevation thereof partly in section, and Fig. 4 shows a modilication. Y 1 Y Y The device asshown in Fig. 1 consists of a casting 1 on the face of which is mounted a cup 2 containing a series of heating elements or spines 3. The bottom or under surface of the casting is grooved or hollowed out as shown :in Fig. '2 so that this surface will conform withthe surface of the inlet,

manifold. The casting` 1 is normally held in this position against the inlet manifold 4 by means of the spring loop 5 the ends ofY which are formed in the coils 6 and fastened Specification of Letters Patent.

the Vnuts 7. LVWhie this type of resilient clamping meansis shown in connection withV the manifold heater, it is evident that other forms of clamps, or hoidin means V"eouid be used without departing rom the spirit of. the invention herein set forth.

An insulated hande 8 may be provided to lift the manifold "heater and place the saine in position after it has become heated, but this may be dispensed with if desired, as the same may be placed in position by the gloved hand of the'A operator.

1 The operation of the device is as follows: l'V hen it is desired to use the manifold heater, the same is remo-ved from its normal position on the inlet manifold 4, by swing! ing the spring loop 5 into the osition shown in dotted lines in Fig. 3. T e casting 1 is then placed upon any Hat surface and a small quantity of gasolene is poured into the cup 2, and ignited. The heat of com bastion of the gasole-ne is readily communicated to the casting 1 by means of the spines 3, and when the gasolene is burned out the heater is lifted by means of the insulated handle 8, or the gloved hand of the operator and placed in position upon the inlet manifold 4. As the bottom surface of the casting' 1 is in conformity With the exterior surface of the inlet manifold 4, and the spring VV5 tends to hold these surfaces in contact, the heat contained in theV castin givennp to the iniet manifol with the re- 1 is readily sult that the mixture passing therethrough is readily vaporized, and the en 'ne is therefore easily started. While t e manifold heater as herein disclosed is shown in connection with a Ford engine, it Vshould be understood that the same is applicable to any type of internal combustion engine motor, it only being necessary to so shape Vthe bottom surface of the casting 1 so that Vrheatiiig elment consists of a base plate 1,

grooved or hollovved out as previously described to conform to the surface Yof the inlet n'ianifgld.H VV.liglouliited upon the flat surface of the heating element l, 'by means of the screws or bolts 9, 9,'is the integralcast-V ing 1 carrying the cup 2 and spines 3. With the manifold heater constructed as shown in this modification it is also capable of use as a vulcanizer, as the bolts orscrews 9, 9 may be loosenedV sufficiently to allow a tube and patch to be inserted between the elements 1 and 1a, the screws 9, 9 being again tightened, the device being then placed on a table or other flat surface, the necessary quantity of combustible fluid placed in the cup 2 and the process of vulcanization carried out. It shouldrbe noted in this respect that when the structure is used as a Vul- 'canizeig the grooved portions of the base plate 1a permit a circulation of air to take place, thereby assisting in keeping cool the lower portion of the tube undergoing vulcanization.

W'hat we claim is:

1. In an inlet-manifold heater for internal combustion engines, the combination with a heat-retaining and transferring clement, means for holding the same in contact with the manifold, said element being adapted to be heated when disengaged from the manifold.

2. In an inlet-manifold heater for internal combustion engines, the combination with a heat-retaining and transferring element, of clamping means to hold thesame in contact with the manifold, said element being adapted to be heated when disengaged from the manifold and said clamping means.

3. In an inlet manifold heater for internal combustion engines, the combination with a heating element, of clampin means to hold the same in contact with t ie inlet manifold of an internal combustion engine, the bottom surface of said heating element being shaped so as to conform with a portion of the exterior surface of the inlet manifold, said heating element having the upper surface thereof formed into a cup adapted to hold a combustible when said element is disengaged from the manifold.

4. In an inlet manifold Vheater for internal combustion engines, the combination VWith a heating element, of Vclamping -means to hold the same in contact with the inlet manifold of an internal combustion engine. the bottomsurface of said heatingeelement being shaped so as to conform Wtlia portion of theexterior surface/of the inlet manifold, said Yheating element having the upper surface thereof formed into a cup adapted to hold a combustible fluid when Genios et this potent me; be obtained for said element is disengaged from the manifold, and heat conducting members located Within said cup.

5. In an inlet manifold heater :for internal combustion engines, Vthe combination with a heating element, of clamping means to hold the same in contact with the inlet manifold of an internal combustion engine, the bottom surface of said heating-element being shaped so as to conform with a portion of the exterior surface of the inlet manifold, and a cup carried by the upper surface of the heating element adapted to hold a combustible to impart heat to said heating element w'hen detached from the manifold.

6. In an inlet-manifold heater for nter nalr combustion engines, the combination with a heating element, of clampingmeans to hold the same in contact with the inanifold, said element adapted to be heated prior to engagement with the manifold.

7. In an inlet manifold heater for internal combustion engines, the combination with a heating element, of clamping means to hold the same in contact with the inlet manifold of an internal combustion engine, a cup carried by the upper surfaceof the heating element and adapted to hold a combustible fluid to impart heat to Vsaid heating element, the sides of said cup being Vso tapered that no combustible fluid can be placed in or remain in said cup when the heating element is in contact position with said inlet manifold.

8. In an internal combustion engine, the i combination with a cylinder block of an inlet manifold, bolts projecting from said cylinder block, manifold brackets mounted upon saidV bolts to hold said manifoldin engagement with said cylinder block, a heating element for said inlet manifold, and clamping means carried by saidY bolts and adapted to hold said heating element4 in resilient contact With said inlet manifold.
